Indoor versus outdoor temperature
Opening helps only when the incoming air is useful. Ventilate compares your indoor reading with current and forecast outdoor temperatures.
How it works
Advice built around your home, not a generic forecast.
Ventilate turns the conditions outside and the details inside your home into a clear next action for each window and fan.
Window orientation and sunlight
A sunny west-facing window behaves differently from a shaded north-facing one. Orientation and sun exposure shape each recommendation.
Home layout
Rooms, floors and openings affect how air can move. Your layout helps Ventilate distinguish cross-ventilation from a single opening.
The fans you have
Add your available fans and Ventilate can suggest where to place them and which direction to point them to support airflow.
Weather transitions and warnings
Forecast changes help identify the next useful cooling window. Rain, tropical nights and other warnings can change the plan.
Optional environmental context
Ventilate Pro can also account for outdoor air quality, pollen, UV and humidity when those conditions affect a sensible action.
Trust
Deterministic rules, not generated AI
Recommendations come from a defined rule system applied to your home and current conditions. Ventilate does not ask a generative AI model to invent advice. The same inputs produce the same recommendation, making the reasoning consistent and testable.
From information to one useful action
The recommendation engine narrows many signals into instructions you can use immediately.
